Mechanism and Control of Water Inrush from Separated Roof Layers in the Jurassic Coalfields

Mine Water and the Environment, 2021
Theoretical analysis, numerical simulation, and borehole drilling were used to study the mechanism of four large-scale water inrush events that occurred during the mining of the 1121 working face in the Hongliu coal mine in the Ningdong mine area. We concluded that the working face inrush was induced by water in the bed separations formed by overlying ...

Petrographic characteristics and peat environments of Gashun mine (Jurassic), Hoxtolgay coalfield, China

World Journal of Engineering, 2013
Twenty-two coal samples and eleven parting samples were taken from Gashun Coal Mine, Hoxtolgay coalfield, Xingjiang Autonomous Region, and the samples were analyzed by using optical microscopy. The results indicate that the dominant macerals are vitrinite (av. 76.6%) with minor amounts of inertinite (av. 18.84%) and low liptinite (av. 2.7%), along with
